Goals: This unmanned mission concept would use a variety of spacecraft on the surface and in orbit with the ultimate goal of returning Martian soil samples to Earth. The current proposed campaign calls for a set of three missions:

First a robotic rover would collect a cache of samples.

Then a lander and "fetch rover" would recover the cache and launch the samples into Mars orbit.

Ultimately, an orbiter would return the samples to Earth for analysis in a secure containment facility.
